Preheat the oven to 400°F/ 200°C. Line the baking sheet with parchment paper.
Prepare zucchini: Grate them on the fine side of a box grater. Place them on a clean kitchen towel, gather the towel, and squeeze out the excess water. Place them into the bowl.1 cup zucchini
Meatball mixture: Add ground turkey and all the other ingredients except for the oil. Mix well to combine.1 lb ground turkey + ⅓ cup breadcrumbs + 1 small onion + 2 garlic cloves + 1 tablespoon dill + 1 tablespoon parsley + 1 egg + 1 ½ teaspoons whole grain mustard + 1 teaspoon sweet paprika + ¼ teaspoon red pepper flakes + ¾ teaspoon fine sea salt + ½ teaspoon ground black pepper
Form the meatballs using about ¼ cup of the mixture for each one. You will have about 12 quite large meatballs (Note 3).
Brown the meatballs: Heat the oil in the pan and brown the meatballs in batches. It should take about 2 minutes per side.2 tablespoons vegetable oil
Cook the meatballs: Place the browned meatballs on the prepared baking sheet and bake them in the preheated oven for 7-8 minutes or until they are cooked through.
Check them with an instant-read thermometer – the internal temperature should be 165°F/ 74°C. You can also check by cutting one in the middle.
Notes
Ground meat: You can also make these meatballs with any other type of ground meat: chicken, pork, beef, or a mixture.
Herbs: You can use frozen dill and parsley, or other fresh herbs like oregano or thyme. If you don’t have fresh or frozen herbs, use 1 teaspoon of dried thyme or oregano instead. Dried dill and parsley are not so great, but you can use them if you want.
Meatball size: These are fairly large meatballs. You can make them smaller, but keep in mind they will cook faster, so check them a bit earlier.
